Tfdf on sagemaker printing the loss for each iteration

TensorFlow
,
1

Hi,
I’m using tfdf.keras.GradientBoostedTreesModel with verbos=2, added several metrics: model.compile(metrics=[‘binary_crossentropy’, ‘mse’, ‘AUC’, ‘accuracy’]) , trained with 500 num_trees.

I would like to see the train loss vs the validation loss for each iteration (tree in my case)

I have here 2 problems:
1- In the logs I can’t see the loss after each tree addition, I rather see logs after building few trees.
2- I won’t see all the metrics I added (saw here that it’s not supported)

I tried to used the inspector model.make_inspector().training_logs(), however i encountered a problem of retrieving the model, please find attached log:

[1,mpirank:0,algo-1]:The model at /opt/adva/checkpoints/tfdf/v0/model/ contains multiple YDF models. Please specify the prefix of the intended model. Available prefixes: [‘72a694e546584792’, ‘3d9f0b2ad7984337’, ‘a39992b7f3aa4541’, ‘bdf53386edd64b97’, ‘b729c3f939b14592’, ‘8aef82d8e4434fb8’, ‘7b0eeab2e4e840a3’, ‘cadda57c48874500’, ‘8aeda86d45964712’, ‘0ecb05d742d24dce’, ‘44e569ec76d742ea’, ‘325fb31fa3b54dd1’, ‘3307f0d3ab014532’, ‘77cf5988e9e64ce8’, ‘7f2654b72f7c4b6a’, ‘d4013745082f4abe’, ‘18e7f5be5f8840c8’]

what are these multiple YDF models (the dir is new so how come I have several models there)?

I noticed that after fitting the model is exported without me saving it (the log: Export model in log directory: /opt/adva/checkpoints/tfdf/v0 with prefix cadda57c48874500 ) Is there a way to determine the log prefix of the model and to pass it to the inspector?

Any idea how can I solve my problem and see logs for each tree?

Thanks

Hi @ahad ,

After carefully reviewing your post, I would like to summarize the key points and provide some suggestions to address your challenges.

  1. To see the loss after each tree addition, you can enable verbose logging during training. You can set the verbosity parameter to a higher value, such as 3.This should provide more detailed logs during training.

  2. You can try specifying the desired model prefix when calling the training_logs()

logs = model.make_inspector().training_logs(prefix='72a694e546584792')

I hope this helps!

Thanks.
